I dropped the tv ( Sony circa December 1985)
It fell face down from about 2 feet off the floor. No pieces fell off
of it but now the picture's lower left hand corner is Red-ish and the right hand corner is Green-ish. Fiddling with the buttons hasnt helped change this situation. I would love to fix this. Advice would be appreciated. I dropped it when I was sliding it around the NEW tv cart I got for it because I figured a sturdy cart was cheaper than getting a newer, lightweight tv. Now I have to wait for someone to come home to grab the other side's HANDLE so we can lift this back on the cart. |

Try using a degaussing coil, since you really don't have anything to lose. Unfortunately, it is most likely that the internal components of the picture tube have been shifted from the shock of the drop. This means that the tube is internally damaged and the only way to repair this problem is to replace the picture tube. DO NOT continue use of this set! This kind of picture tube damage presents a potentially serious implosion hazard as the internal structure of the picture tube is compromised, thus it's ability to resist implosion may also be affected. Replacing the picture tube is not going to be practical and it certainly isn't going to be cheap. Your TV set is very old so replacement tubes may no longer be available. Even if they were, it would not be worth the effort and money given the age of the TV set. Replacement tubes are expensive as well as the labor to install the tube and recalibrate the set. There may be many other components in the TV that could have drifted out of tolerance so much that the set could develop another problem after the new picture tube installation. Repeating the recommendation of another poster here, I think it's time to consider buying a new television. IMO, Sony is still an excellent choice, if not one of the very best choices. - Reinhart |

To be honest with you, I don't know. It has been many years since I worked
in a TV shop. And even shooting the tube does not guarantee that it is going to work. Kinda a last shot before disposing the TV, or replacing the tube. But one of the other guys on here, may be able to give you an estimate, and if it even can be done.... Hope that helps, Rick "Accidents HAPPEN" wrote in message ...

You can still use the set if you don't mind the corner discoloration. If the
glass didn't implode when it hit the floor, it sure isn't going to happen by simply watching TV. Shooting will not help this problem. If the discoloration is minor a reputable shop can add correction magnets to the back of the tube. Chances are slim though. You're tube is damaged. Ron |

I think you can forget about any possibility of a repair being
succesful. Sony shadowmask tubes are particularly susceptible to damage after being dropped. Sony Trinitron picture tubes do not employ a shadow mask. They employ an aperture grille. There's a substantially big difference between the two. See this account from a customer who had his Sony TV damaged during a furniture removal. http://www.epinions.com/content_109848792708 How convenient in that you disregard various details in the story which tells us more about what happened and ultimately puts the credibility of your claim into question. You didn't even properly specify what was going on which led to the damage. This wasn't a mere furniture removal. This was a transcontinental move from California to North Carolina. That's literally a move from the west coast to the east coast of the United States! That's one hell of a furniture removal! First off, most moving companies, such as Mayflower or Bekins, have a notorious reputation of destroying items during transit. Secondly, the story reveals certain details about how the TV was damaged. Upon examination by a certified Sony repair professional, the TV set yielded substantial physical evidence of mishandling. A small crack on the casing of the TV and a severely damaged mainboard both suggest that the set suffered a substantial impact, likely due to mishandling. Those details that you did not note were present in the Epinions review. The Epinions article you've presented doesn't support your claim against Sony TV sets. All the article does is suggest that a TV set can be severely damaged by careless movers. Any other brand of TV would have yielded similar problems had they been mishandled in the same fashion. If there was a drop substantial enough to damage the mainboard and crack the casing, it's likely that the tube will have been damaged as well. - Reinhart |

Listen up, don't be a nit picker...
Specifying very significant details that you either ignored or didn't factor is not nit-picking. Reading your post establishes the idea that Sony TV sets are not durable. Posting a hyperlink to an Epinions article with a very vague description of what the post was about tends to strengthen the impression you are trying to create with your wrtiting. However, when someone with any sense with electronics repair reads the article, they'll find the particular scenario from that story would cause damage to ANY TV set. The point of that story is simply that after mishandling by (in this case transporting) the sony tv had sustained some damage to the picture tube which could only be repaired by a tube replacement at great expense. But what degree was the mishandling taken to? Apparently, according to the Epinions article, a lot. The story also describes that the mainboard had to be replaced by the technician just to get the set to turn on in the first place. If a drop was enough to destroy the original mainboard, then it may also be enough to shift the innards of a picture tube. The larger the tube, the more susceptible it is to this kind of damage. I don't care if it's a Sony, a Toshiba, a Panasonic, or a Loewe. If a drop damages the mainboard to the extent that it won't work anymore, then it's likely that the tube could be trashed as well. I stand by my arguments and feel that your claims are in error by bad example. - Reinhart |

I dropped the tv ( Sony circa December 1985)
As I said I could have spent time cutting and pasting only the
relevant parts and if you were not intelligent enough to compare the fact that the OP "dropped his Sony TV some 2 feet" and the Epinions article that considerable damage resulting in the need to replace the picture tube due to mishandling, then I can't help you. Quotes taken verbatim from the Epinions article: Before the packing: "On the day of the move, Excels packing team came to my house in Union City, CA to wrap and box nearly everything in the house. While they worked, my daughter was watching a show on our 36€? Sony flat-panel TV, which was hooked up to our home theater system. When it came time to prepare the TV for moving, they directed us to unplug the TV. At that point, the television was obviously in perfect working order." After the move: In particular, the damaged items which prompt my dissatisfaction with Excel Moving Services we The Sony Wega TV described above, the television simply would not turn on" Interesting. The TV set would not turn on after the move. "I took the television to Audio Video Specialists in Durham, NC, who is a Sony-authorized repair center. Kevin, the repair engineer at AVS diassembled the television, replaced the PC logic board with one from another television in his shop and determined that the TVs cathode ray tube (CRT) had a damaged €˜shadow mask," The technician had to replace the mainboard first before discovering that the picture tube was damaged. On a set that is as well built as a Sony, it would take a fairly substantial shock to inflict the kind of damage on the mainboard that would keep the television from powering on in the first place. Sony sets of that size typically have well secured mainboards and extensive metal shielding covering all over the outside rear of the picture tube. They also have fairly substantial structural support due to the sheer weight of a large TV, especially Sony sets. "He noted that the only way such damage could occur was by being dropped and wrote 'Shows Signs of Shipping Damage' on his report to Mayflower. Only after reassembling the TV and while attempting to use the bezel as a handhold while moving it to another location in his shop did he notice the slight crack in the decorative bezel below the TV. He also noted the cracked bezel on his report." This means that the drop was substantial enough to damage the mainboard, damage the picture tube, and crack the casing. All these parts cannot be damaged by a small drop or small incidences of shock, especially the mainboard which is typically immobolized fairly effectively on a Sony TV. Since the shock was substantial enough to damage the mainboard, despite how it was assembled into place, that same shock would likely be more than enough to wreak havoc on the innards of the picture tube. It is a sad fact that any tv, when dropped or roughly handled during transport (ie, dropped such that only minor indications of physical damage were noticeable) is highly likely to distort either the shadow mask or the aperture grille. That goes against your claim that specifies only Sony tubes as being susceptible. "Sony shadowmask tubes are particularly susceptible to damage after being dropped." At first, you claim that Sony tubes are particularly susceptible to damage when dropped. Now you come out and say that "any TV" will likely suffer damage to the picture tube if subject to excess shock. You change your statement from a specific accusation to a broad generalization. And, I say your statement of Sony tubes being "particularly susceptible to damage after being dropped" an accusation because there is no other definition of your statement. It is an accusation, pure and simple. If you disagree, then you need to go back to school and study English. It seems you are not able to decipher the relevant aspects in a story and throow out the bits which are not relevant to the original priblem posed by the OP. And you are too ingrained on your opinion that you are unable to view it in much broader context. You make an accusation and support it with a story that reveals more about what happened and consequently downplays your claim. You didn't read the story well enough to understand everything that could have happened to cause all that damage. First off, the author of the Epinions article hired a moving company that's as trustworthy as Dan Quayle is proficient at spelling "potato." (Since you live in Australia, you won't get this joke unless you remember that Dan Quayle was Vice President under George Bush SR. [not to be confused with his son and current president George W. Bush] from 1988 to 1992 in American politics who earned a distinction of being an idiot by spelling potato "potatoe" at a public speech.) Second, the TV traveled approximately 2800 miles from California to North Carolina. Anything could have happened between those locations during the journey that may have caused the TV set to become damaged. This is exacerbated if the items were not properly secured in the trailer. Anything, like abrupt maneuvering, potholes, sudden braking, and the like can create the potential of the load being dislodged and allowed to jostle inside the trailer. Third, moving companies, like Mayflower, have storage facilities where items may be taken out of the truck and placed in storage rooms until the items are ready to be delivered to their final destination. The labor force hired to do the moving of the items out of the truck and back into it may not have been as careful as the folks who packed the truck back at the starting point. Forth, substantial damage to items at the hands of moving companies, especially if the load traveled a long distance, are not uncommon occurances in the United States. People have had TVs, sofas, tables, guitar amps, chairs, console stereos, lamps, paintings and pictures, and the like damaged or destroyed during transit. I've read about them and I've seen the damage done to such traveled items first hand while working at a repair shop. And I stand by my argument that you obviously need every i dotted and every t crossed and you are unable to sift wheat from the chaff in a story. And I guess you like being too lazy and prone to premature condemnation. - Reinhart |

|Reading your post establishes the idea that Sony TV sets are not durable.
??? How you can draw that assumption from a story of damage to a Sony TV during transport, I can't imagine. What you typed, verbatim. "Sony shadowmask tubes are particularly susceptible to damage after being dropped." You typed this. Read it, and read it again. Your wording here most certainly suggests what I claim about your contention. It is an accusation that clearly narrows down to the subject. You clearly typed that Sony picture tubes are "particularly susceptible to damage after being dropped." You don't cite what kind of drop and you don't cite to what degree, you just cite "a drop" which is a generalization. You make a clear accusation with a broad and general description that allows the impression that "Sony TVs are not durable" to be made in the first place. If this was not the intended response to your statement, then you either need to brush up on your writing skills or you could give Micheal Moore a run for his money. The story is more to do with the reliability of the transport company and the care which they provide to the goods they are transporting. If you recognize the story to be off-topic and unrelated to begin with, then why did you bother to bring it up in the first place? I am not trying give any impression other than physical shock (ie dropping or rough handling) to a tv can cause internal damage to the picture tube which requires this item to be replaced at great expense. Now you made it more logical, but contradictory to your original claim. Now you state that any TV will sustain internal damage in the picture tube from a severe shock, which was the statement I originally made in response to your statement a day ago. My response, as quoted: "The Epinions article you've presented doesn't support your claim against Sony TV sets. All the article does is suggest that a TV set can be severely damaged by careless movers. Any other brand of TV would have yielded similar problems had they been mishandled in the same fashion. If there was a drop substantial enough to damage the mainboard and crack the casing, it's likely that the tube will have been damaged as well." Originally, you stated clearly and specifically that Sony picture tubes were "particularly susceptible," now you say that all TVs will sustain damage in a generalization. If you were to hold on to your argument, you would have to say that "all TVs would be vulnerable, but Sony TVs are more susceptible than anything else." Since you are not wording your recent responses like this, you're not even supporting your original contention anymore. Yet, you still want to get into a ****ing contest about this. Unless it is established specifically what sort of "rough handling" the particular Sony TV was subjected to, we can't draw that conclusion, and I did not infer what you assume I did. Then why did you make the accusation about Sony TV sets being "particularly susceptible" to drop damage to begin with? BTW, I am a strong supporter of Sony products and my household boasts these items; And what relevance does this statement have to this subject? Being a Sony supporter or not is irrelevant. Getting the facts straight, on the other hand, has been taking place on this thread. How many Sony items do you have? Okay. Since we have to get into a ****ing contest about equipment: Sony KV-27S66 television Sony SL-HF400 SuperBeta hi-fi VCR Sony SL-HF2000 SuperBeta hi-fi VCR Sony SL-20 Betamax VCR Sony SVO-160 VHS hi-fi VCR Sony SLV-575UC VHS hi-fi VCR Sony SLV-750HF VHS hi-fi VCR Sony MDR-600 Monitor Headphones Sony CPD-200GS monitor Sony CPD-100SF montior Sony SCPH-1001 PlayStation Sony SCPH-30000 R PlayStation 2 Sony MDP-1000 LaserDisc player Sony STR-DA4ES Digital Surround Receiver Sony DVP-S360 DVD/CD Player Sony ICF-C121 Clock Radio Alarm Sony CDX-C560 MobileES car stereo Sony CRX-140E Spressa IDE CD-RW Sony CCD-TRV58 Hi-8 Camcorder Sony SPP-95 Cordless Telephone Sony SPP-S9101 Cordless Telephone Sony M-540V Microcassette Recorder Sony CPS-88S Multiband Radio Boombox Sony D-105 Portable CD Player Sony WM-FX403 Radio/Cassette Walkman Sony WM-FX38 Radio/Cassette Walkman Sony WM-FS191 Radio/Cassette Sports Walkman Sony WM-EX102 Cassette Walkman Apparently, a hell of a lot more than what you've got. And I totally expect a backstabbing response like "oh, you own so many Sony products, it's so obvious why you were in disagreement with me." I'd hate to burst your bubble, but I also own many other electronics made by other brands, mainly Japanese (Pioneer, JVC, Panasonic/Technics, Toshiba, Yamaha, Onkyo, Mitsubishi, Akai, Hitachi, NEC), that have been as good, if not superior, to some of my Sony items listed. With such experience, I can assure anyone that if they want quality electronics, they should buy Japanese unless they are willing and able to blow a small fortune for exotic stuff from brands like Sunfire, Krell, Bryston, Runco, Linn, Proceed, Meridian, Bang and Olufsen, Seleco, Lexicon, and various other brands, many of which the general public do not know exist. - Reinhart |

I dropped the tv ( Sony circa December 1985)
I already addressed this. My memory may be flawed, but I am pretty
sure I read what I read in a Sony repair manual or training manual. But, here's the thing. The person said that Sony picture tubes are particularly susceptible to drop damage, indicating Trinitrons are more sensitive to a much greater degree. Sensitive or not, ANY CRT picture tube, be it Trinitron, Diamondtron, or a shadow mask WILL sustain damage if dropped, PERIOD. Drop any large CRT display from about two feet and the guts of the tube will be shifted. Furthermore, if a drop is bad enough to damage a mainboard, what do you think it will do to the picture tube, regardless of brand? - Reinhart |

If my memory is correct, there are specific
admonitions with regards to degaussing Trinitron CRT's. If they are more sensitive to that which is totally benign to a shadow mask CRT SNIP Shadow mask tubes are also just as vulnerable to internal damage from strong magnetic influences. If you use a powerful rare-earth magnet or a magnetron, you can destroy a CRT, aperture grille or shadow mask. Normal degaussing done properly, however, should pose no risk to any CRT. - Reinhart |

I dropped the tv ( Sony circa December 1985)
I simply said (in error) that Sony "shadow mask" (should have been
aperture grille) tubes are particularly susceptible to damage after being dropped, and this is true even for a distance of 2 feet as in the OP's case. You drop just about any TV from two feet, you will damage it. If we look at Sam Goldwasser's repair faqs I've read that before a long time ago. Lightly tap any trinitron tube item with your hand and you will notice the picture shimmer. And I know that's because of the vertical wires. The same effect can not be achieved so easily with a non aperture grille tube item. Maybe because a shadow mask uses an alloy sheet that is finely perforated? This is evidence of suceptibility to vibration. That means that the **wires** will move from the vibration, but what about the support structure that holds the whole works together? The wires themselves cannot become misaligned. The entire support structure must be shifted to cause the wires to move out of position to cause purity problems. In order for the aperture grille tube to have similar strength and resistance to implosion it has to be made of thicker glass than an equivalent shadow mask tube. Actually, this would apply to the current generation of Trinitron tubes, which are flat face CRTs. Also, remember that flat face shadow mask CRTs also require additional materials to support the tube structure to prevent implosion, since the structural benefits of a dome face tube are lost in this case. Anyways, previous Trinitron generations had partial reinforcement from the cylindrical shape of the tube face, which supported the tube structure on the horizontal axis. Now if two similar sized tubes, one of either type, are dropped through the same (assume 2 feet) distance, which one do you think is going to make a bigger impact when it stops? And my question is "what is the point?" Remember the point I made about dropping TV sets from two feet. I don't care if it's a Sony or a Panasonic, a drop like that will cause damage to many parts, including the picture tube, PERIOD. A 32 inch Trinitron tube will weigh more than a 32 inch shadow mask tube. But, a 32 inch shadow mask tube is still a heavy part that will be damaged from excessive shock. (ed - Note the "during transportation". Have you seen similar instruction to correct misalignment of the shadow mask in a shadow mask tube following transportation?) No. Typically, because if the shadow mask is misaligned, there is no way to correct it short of replacing the picture tube. At least, according to your source, there is a procedure to correct minor misalignments with Mitsubishi tubes (and apparently, Mitsubishi tubes only) whereas a misalignment to any degree with a shadow mask and probably even a Trinitron cannot be resolved. Damper Wires: The two faint horizontal lines that may be visible on the screen are actually the shadows of steelwires called Damper Wires. All Diamondtron U2-CRT based monitors have these wires for structural reasons." They have them to dampen resonance that can cause problems with the picture during operation. Have you ever tried to stop a guitar string from making noise by applying pressure to it with your finger? Same principle. Even the manufacturer is aware of the susceptibility to shock and is careful to give suitable instruction regarding this point during installation. I would advise that for any TV. A drop is never a good thing on any TV set, and not just because of the tube. You not only jump to conclusions but you read into my statement things which were not intended nor were inferred, except in your own mind, that is. Whatever. Surely, any reasonable thinking person would read the story and discarded the parts which were not relevant to the OP's post about dropping his tv. But you don't know what the TV would have been through in its travels from California to North Carolina, so anything between departure and arrival could have caused the damages to the TV. Because there was little evidence that the TV had been subjected to physical shock (by dropping, for example) during transport. The owner was not aware that it was damaged other than the set failed to switch on. What can damage the mainboard to the point where it wouldn't switch on? Cold solder joints? I could buy that, except that doesn't explain why the board had to be swapped for a replacement from a parts unit. I simply said the tubes are susceptible to damage due to dropping, and this applies to Mitsubishi tubes as well. And Philips, and Toshiba, and Hitachi, and RCA, and Zenith, and any other manufacturer of video CRTs. You are aware that there have been instances of drop damage with shadow mask tubes that made them show Atari-esque rainbows over the entire picture? Also, Mitsubishi made both aperture grille and shadow mask tubes. However, their Diamondtron tubes were used only for computer monitors. You are again making assumptions without any evidence. Read the Epinions article. Why did the mainboard require replacement? Again, the tech had to replace the board to get the TV to turn on! Before the TV was ever loaded into the moving truck, it was working perfectly. In what ways can the board be damaged to the degree where it became necessary to replace it than repair it? Answer that. There is no indication that the original board was damaged in any way. That excerpt from the Epinions article was from the author of that article. Sometimes, you can have a board that appears okay but have developed cracks on the board that were enough to sever the traces. And, sometimes, these cracks don't appear very obvious unless you know what to look for, such as a slightly whiter discoloration of the board's normal color that travels as a fine line on the board. I would assume that Kevin was simply trying the "swap and hope" method of repair without any evidence that there was anything wrong with the original board. Then why would the TV set no longer turn on after it was unloaded from the moving truck? It was working when it was loaded into the truck. The only evidence of physical damage to the TV at all was to a decorative bezel, not exactly "the casing" in my opinion But it is part of the casing. See, you are wrong again. I did not say "Sony TV sets" at all. No. You said Sony picture tubes. But, you can only find Sony picture tubes in Sony-manufactured video equipment. You cannot find a Sony Trinitron picture tube in an RCA, a Philips, a Hitachi, a Toshiba, or anything except on a Sony TV or computer monitor. As for other brands of **computer monitors** that use Sony picture tubes, those monitors are also completely OEMed by Sony, with Sony designed and manufactured electronic parts, for those brands. So, in essence, you are implying that Sony TV sets are more susceptible to drop damage. This is due to the simple fact that no other make of TV set uses Sony picture tubes other than Sony themselves. Unless you can show me a picture of a different brand of TV set that uses a Sony Trinitron tube legitimately with everything around it not completely designed by Sony themselves, then it is YOU who needs to get the facts straight. Nothing could be further from the truth. I love 'em, but they must be protected from shock and vibration as Sony themselves instruct. But that's common sense advice when handling ANY television set. It is relevant in order to see what your real beef is. I asked you that question in order to establish if you have some sort of sensitivity to criticism of Sony products. You responded in the manner I expected... And you replied in exactly the manner I expected and made clear in my previous post. You stabbed me in the back (which is a figure of speech). You used the ****ing contest for me to make a list of products I owned so you could turn the argument around and make me look like some blind fan. Curious, that you would turn to this even though you yourself are an admitted supporter of Sony products, which should make you no better than me in your world. The point of my rebuttal is not in defense of Sony TV sets. But, rather, to make clear that Sony TV sets are not special in requiring careful handling. ALL TV sets require careful handling to prevent damage for more reasons than the picture tube, although the picture tube is most definitely a major area of concern from mishandling. To imply otherwise allows inaccurate impressions to be drawn by those unfamiliar with the technology, which can brew unfair biases. Anybody who has this amount of Sony products is obviously a Sony Sycophant and I suspect you are extremely sensitive to anybody making any statements which you perceive to be criticising a favoured manufacturer's products Backstabber. You are correct that I was trying to establish this fact. Backstabber. To set your mind at rest I would have all Sony products too if I could afford them. Okay, you're a backstabber and a "Sony Sycophant." On the other hand it is obvious why you can't see that even Sony products might have some weaknesses On the contrary. I collect electronics, and not just Sony. As for Sony, I am selective. When I buy Sony, I tend to try and get higher end models. High end Sony products are some of the best you can buy. But lower end Sony products are, quite simply, some of the worst overpriced pieces of junk I have ever seen since Bose loudspeakers. There are exceptions, but with Sony, the more you pay for a higher end model, the much better off you will be. One of the absolute worst receivers I've ever listened to: Sony DE series receivers. Some of the absolute worst CD players and tape decks I've listened to were Sony. Sony speakers: even Jensen speakers sounds better than Sony speakers! If you ever buy Sony audio, only buy from their excellent ES line. Sony video is great but Sony audio, save the Elevated Standard line, is ABSOLUTE GARBAGE! One of the best receivers I've listened to: Sony STR-DA4ES, and I bought that because I could get it for $300 instead of $700-$1000 at retail. But, I don't have any other Sony audio components other than Walkmans and a Discman. The Walkmans almost never see use as I spin CDs mostly, and my Sony Discman collects dust as my Panasonic portable CD player has better sound quality and durability with a longer battery life and superior defect tracking. My Sony KV-27S66. I bought two of those for $30 as defective items. I built one good one from the two. Although, I prefer Sony TVs because of positive experiences with them in production uses, the price that I was able to get my set for plus what I could do to have a working TV was what sealed the deal for that particular set in my case. Sony computer monitors. Same deal. I've had great experiences with Trinitron and was presented with good deals, $5 and $25 respectively, so I snatched them up. One required mainboard work as it had a small crack that severed one trace. The other had no problems. Sony VCRs. I got them when they were broken. The SVO-160 required repairs to the capstan motor and the power supply. The SLV-575UC and the SLV-750HF also required capstan repairs. I repaired them and I have had no troubles since. As for Sony Beta VCRs, Sony makes better Betamax decks than Toshiba, NEC, and Sanyo. Talk to any Betaphille, and they will say the same thing. Sony MDR-V600 headphones. I got a set of MDR-V600 headphones that sell for $130 MSRP for $10 at a pawnshop. I knew what they were and I snatched them up. Best pair of headphones I've used since the Optimus PRO-35. Sony clock radio. Bought it because it was there and had a great deal. It was that or buy a clock radio from a crappy no-name brand that would likely have required replacement after a year or so. Sony DVD player. Bought it because I got a good deal and offered the versaility that I needed with performance I liked. It has dual video and audio outputs, SP-DIF coaxial and TOSLink optical outputs. Boots up discs blazingly fast and has excellent video quality, save the minor problem with chroma upsampling. Sony Walkmans. One was bought new, two were bought used for low prices, while the remaining one was given to me. All sit and collect dust. Sony Discman. Given to me. Collects dust because I didn't like the sound quality (gritty with a fatiguing effect) compared to my Panasonic discman (smooth, detailed, lush, and accurate which isn't bad for a portable). Sony car stereo CD player. Given to me, and I use it because it's a MobileES model, meaning it's built better and sounds better than regular Sony car stereos. Sony CD-RW drive. Needed a CD writer and got an unbeatable deal on it so I bought it. Sony camcorder. Pawnshop buy. Needed a cheap Hi-8 camcorder that wasn't old. The only choice they had was the Sony CCD-TRV58. It was either that or buy an older camcorder with caps that already failed for the same price. Plus, I also had a good extra battery for it that came from some bozo's Sony Mavica that accidentally got dipped in the ocean. Sony cordless phones. One, I bought used for real cheap. The other, given to me as it required repair. Severed connection to the handset speaker, which was repaired by a simple resoldering. Sony microcassette recorder. Given to me. Sony CPS-88S boombox. Given to me, and it's unique in that it receives shortwave in addition to FM and AM. Sony MDP-1000 LaserDisc player. I needed an LD player cheap and that was available. It's been relegated as a spare player by a superior Pioneer DVL-700. Talk to any LaserDisc buff and they will tell you that Pioneer players rock while Sony players suck. In my experience with LD players, that assessment is pretty accurate. While the MDP-1000 wasn't a bad player, other examples of Sony players that I've seen were uttery terrible, except for the MDP-605 and MDP-650. Sony videogame systems. If you are into videogaming, then you should be aware that Sony consoles have some great games available, which is also true of their competition. And that pretty much explains how I got all those Sony items.

True. But that fact is hitting the European and American brands much harder than the Japanese brands. Also, there is also the factor of engineering. Lower end items, as well as most European and American items typically receive attention very much like how the American automakers work: "design it until it's just enough to work." Plus, this is a reason why I buy only higher end Sony products. Even though a few ES components have been built in Malaysia, they seem to still be crafted with care and usually yield superior engineering over the conventional consumer line. However, lower end ES products, particularly CD players and tape decks, share many things with the regular Sony stuff, including transport designs. Many of them are simply overpriced and are no better in performance than more common brands in my opinion. Also true. The late Julian Hirsch made such a comment. However, you usually still have to spend more to get more quality for audio, even for mass-produced items. This doesn't necessarily indicate that you will get more from the more expensive and lesser-known brands, but making a point that the lowest end Denon receiver will beat the crap out of the lowest end Sony receiver. This is because Denon puts more dilligence towards their craft in terms of audio equipment than Sony's regular consumer lines, and that extra dilligence costs extra money. - Reinhart |
